Rating stars for the iphone
"Draw Something" uses a special screen to ask you to rate the app with five stars, which pops up after a certain amount of play. The screen does not seem to use the usual AppStore process. It specifically gives you the option of five stars or cancelling.
Does anyone know how this is achieved? I thought you could not do this programatically.
I'm pretty sure it doesn't actually post the ratings from within the app (that would require them to know the user's iTunes password and it would also most certainly violate Apple's guidelines).
It's just clever wording that's supposed to suggest to the user that they couldn't post a 1-star review from the app, even though it probably just directs them to the App Store ratings page, where they could enter whatever they want.
